Drug toxicity, also drug reaction, in pathology is often a diagnosis of exclusion. Few drugs leave a distinctive histomorphologic pattern.
This article covers a few of the distinctive histomorphologic pattern and links to other articles that deal with specific organ systems.
General principles
A drug/toxin reaction should be considered if there is:
- Ingestion/exposure.
- An appropriate temporal relation.
- An empirical correlation between the drug/toxin and the pattern.
- Worsening with re-challenge.
- Improvement with removal of exposure.
- Pathologic pattern matches with toxin.
- Drug/toxin detected within individual.
Site specific
Liver drug toxicity
Stomach
Small bowel
Specific drugs
Sodium polystyrene sulfonate
- AKA Kayexalate (trade name).
General
- Used to treat hyperkalemia.
Microscopic
Features:[1]
- Purple blobs on H&E stain - look somewhat like calcium phosphate.
- Can cause focal necrosis.
